I have been going through my paperwork for our hols and we have paid to pre book our seats but theres no info on how to do it or what website to go on. I tried google for thomas cook booking seats and it took me to their site for booking a holiday. We're flying with thomas cook, if anyone can tell me what I'm doing so I dont do it wrong I would be extremely greatful.

is that only for thomas cook because i was told when i booked with thomsons it was still 90 days to book your seats (we have already paid to be seated together) but i really want to 2 rows of 3 behind each other at a window if possible...we are going on the new dreamliner so should i go back and ask them about it?
